The Riedel SOMMELIERS BLACK TIE series wine glasses are the Grand Cru Wine Glass Collection from a pioneer in the wine glass industry. Riedel SOMMELIERS BLACK TIE series was launched in 2008 to celebrate 50 years since the introduction of the BGC glass. SOMMELIERS BLACK TIE series glasses are highlighted by a tall black stem, a sturdy base, executed in lead crystal, mouth blown in Austria. They are dishwasher safe, but hand-washing is recommended for all fine Riedel glassware. It is one of our most exciting collections.
